It really is valuable, which is why I hope I'm not too addicted to music when I finish my zen tent. So binaural beats have been giving you interesting results? I've always wondered if they leaned toward more pseudo-nonsense or not - maybe I shouldn't pre-judge too quickly. They're easy enough to acquire and try.
PS I got these waterproof earbuds a while back. I can attest to their sound quality - pretty good for $17. I was worried they'd be absolute shite. I'm not the heaviest audiophile but I do hate super crap earbuds so this was a relief.
